Rosa was 2-for-4 with a double and a home run on Sunday, driving in three runs for the Cubs in their 5-3 win against the Lakeland Flying Tigers.
"He's been struggling lately with his swing," Daytona manager Buddy Bailey said. "Richie (Zisk) and I addressed it and he was able to bring it to the game (Sunday)."
Rosa has continually been working to rehab his hamstring and, apart from Sunday, has struggled the past few games at the plate.
"He has gotten a bad habit of upper cutting in his swings, when a week or 10 days ago he was hitting well," said Bailey. "Richie worked with him and got it smoothed out (on Saturday)."
Rosa has also been getting some help and insight from athletic trainer Bob Grimes and says things are coming along fine.
"We've been doing a lot of stretching and a lot of massages. I jump in the hot tub before the game and stretch it throughout," said Rosa.
"Bobby is doing a good job with me."
Rosa spent the entire 2008 season with Class A Peoria in the Midwest League, batting .293 with seven home runs, 58 runs scored, 81 RBIs and a league-leading 43 doubles in 128 games.
Through 10 games this season, he is batting .276 with one homer, four doubles and 10 RBI.
Because Bailey has had his hands full with several players who have started to heat up recently, he's been tasked with moving players around to try and get everyone at-bats.
He says that Rosa adds a dimension to his team that he is grateful for.
"When you give your manager flexibility, it adds to your stock as a player," said Bailey. "Good thing about Rosa is that he can play more than one position. That gives me a chance to get people like Marquez Smith in there who's hitting well right now, too."
Rosa has played first, third, and has also been the DH for Daytona this season.
"I believe I'm comfortable at both (first and third)," said Rosa. "I need to feel comfortable. Wherever they put me, that is where the team needs me to be. So I need to make sure I feel comfortable so I can get the job done."
Rosa, who went through a 0-for-8 drought in the beginning of the Lakeland series, says he's trying to stay confident.
"It's very important for all of us to stay focused," said Rosa. "Richie is always telling us not to throw away at-bats and to stay focused until the end."
This very mindset is what might have helped him on Sunday as Rosa hit a home run in the third inning with none on and two out. He says he is still pushing himself in every at-bat.
"I think I could have focused a little better in my last at-bat (Sunday)," said Rosa. "(Pushing himself is) something I really need to focus on doing."
